1.0.0[][src]Trait core::ops::Rem

#[lang = "rem"]pub trait Rem<Rhs = Self> {
    type Output;
#[must_use]    fn rem(self, rhs: Rhs) -> Self::Output;
}

The remainder operator %.

Note that Rhs is Self by default, but this is not mandatory.

Examples

This example implements Rem on a SplitSlice object. After Rem is implemented, one can use the % operator to find out what the remaining elements of the slice would be after splitting it into equal slices of a given length.

use std::ops::Rem;

#[derive(PartialEq, Debug)]
struct SplitSlice<'a, T: 'a> {
    slice: &'a [T],
}

impl<'a, T> Rem<usize> for SplitSlice<'a, T> {
    type Output = Self;

    fn rem(self, modulus: usize) -> Self::Output {
        let len = self.slice.len();
        let rem = len % modulus;
        let start = len - rem;
        Self {slice: &self.slice[start..]}
    }
}

// If we were to divide &[0, 1, 2, 3, 4, 5, 6, 7] into slices of size 3,
// the remainder would be &[6, 7].
assert_eq!(SplitSlice { slice: &[0, 1, 2, 3, 4, 5, 6, 7] } % 3,
           SplitSlice { slice: &[6, 7] });

impl Rem<f32> for f32[src]

The remainder from the division of two floats.

The remainder has the same sign as the dividend and is computed as: x - (x / y).trunc() * y.

Examples

let x: f32 = 50.50;
let y: f32 = 8.125;
let remainder = x - (x / y).trunc() * y;

// The answer to both operations is 1.75
assert_eq!(x % y, remainder);
Run

type Output = f32

impl Rem<f64> for f64[src]
